WILLIAM LINDSAY SIMPSON, essen frninneiseo, CALIFORNIA. ASSIGN'OR TO To all whom lit may c m et I i i Be it lmown that' l, WILLIAM LINDSAY SIMPSON, a citizen of the United- States, and residing in the City. and county of San Frang cisco, State of California, have invented a new and useful Double-Riveting Machine, of which thefollowingis a specification. i

In the operation of riveting with such pneumatic devices as the Boyer riveter or; Boyer gun, it is in many instances the; practice for t'heoperator to applytthe' rivter te'the worker manually toimfanipulatethey pneumatic tool by himself directly applying y it to the work to be riveted; e

In various operations in boiler; shops,- shipyardsand the like, there is'a great deal of work, suchas straight rivet ng, particu larly in the productionelf-fabricated parts of ships and the like, which can heimore readily and expeditiously effected-flay trans-ff porting the plates or other 'elementsto be riveted, after they have been bolted up, directly to the rivetingapparatus, "by anyf suitable means, as by fa oraneonkindred a H I braces supportingmechanism for the oppoapparatus.

Ifoundinv 'practice to. give satisfactory and Figure l.represents a side elevation of 'a' Y shanks of the rivets.

Fig. 2 represents an end elevationofthe machine of Fig. 1, viewed fromlthe right I handside of said Fig. 1. V

Fig. 3 represents a top plan view of the machine of Figs. 1 and 2.

Fig. 4 represents a side elevation (partly in section) on the dotted line H of Fig. 3. It is to be understood that wherever reference is made to these pneumatic hammers or tools, that such reference is to be interpreted as meaning any conventional type of pneumatic riveter, which embodies a hammering piston with or without a distribution valve to control the reciprocations of the hammering piston which impacts upon the Referring now to the drawings :1 desig nates a'foundation or base plateof any pre- .ferre'dcharacter, upon which are erected plurality of vertically disposed alined standards, uprights or steel plates, respectively designated 2 and 3, the 1111161 edges of which are separated a certain distance to form a gap 6, within which the articles to be riveted such as the plates or the like 40are successively introduced and manually adjusted" so that the rivets 4E1 are one by onebrought intoregistry with the opposing rivet sets 11 and 15 hereinafter referred to.

The standards 2 -and '3 are preferably laterally braced or stayed by opposite counterpait'brace plate s,-4 4* of the standard Qfdild 5, 5* 'of the standard 3,bolted angleirons of'the usual character being used to effect the connection of both standardswith the base plate and also with the braceplates. 7 designates a laterally extending frame projecting from-the standardi' to which it i is bolted or otherwiseattached, to the outer end of which is applied a seat 8 for the operator, whose feet ai'ea'da pted to rest upon the foot plates 9, 9 whicli'project laterally *from both sides of the standard 3 and the outer sides of the :brace plates 5, 5*, below the'seat.

Above "these foot plates are located the pedals 30 and 32 which control the valve mechanism for the motive fluid supply, and, are hereinafter referred to. 7

Upon tlie-tops'oi the standards 2 and 3 are supported the two oppositely operating pneumatic rivetei's which I employ, 11 desig- V mating the left hand or fixed riveter and 15 the opposite or right hand coacting longitudinallyadjustable riveter, it being apparent that in the assemblage of said riveters,

one of them is relatively stationary with re-' lation to its support and the other capable of relative adjustmenttoward and away from the other, whereby plates or articles of different thicknesses can be readily riveted.

Referring first to'the left hand riveter 11,

the latter may be 'a typical pneumatic hammer of the Boyer type, which has a handle let to which the supply pipe 27 is coupled, and which is supported within a casing 13 mounted on a tool bed-plate 1O superposed upon and connected -withthe standard 2, and which has a vertical abutment 12 against whichthe handle end of the-riveter abuts when said fixed or stationary riveter is in position.

11 isthe rivet set of the fixed riveter 11 which alines with the rivet set 15 of the adjustable riveter15when both riveters are assembled.

Referring now tothe right hand or adjustable riveter 15, the latter may be a typical Boyer or. other pneumatic riveter similarto saidfixe'd riveter,but' having its handle removed and its cylinder is screwed into a head22, which isitse'lf attached to or integral withfthe outer end of a plunger 20,-t-he pi'stoiihead 21 of which operates within a fixed air cylinder 19-, preferably supported on a: bracket 18 extending outwardl'y from the outer e'dge'of the standard 8 to which it isbolted or otherwise secured.

'21 motive fluid supply pipe 28-which corresponds generally tothe supply pipe 27- of'the handle of the fixed tool conveys the motive fluid into thetool head 22, so that when the two riveters are in operation or in operative proximity, he motive fluid supply into both of them will through 'asuitable distribution valve,occasion the reciprocatioiis of "the hammering pistons .upon the rivet-sets of the respective riv- 'toward or from the fixed riveter 11 to occasion the desired separation of the two rivet sets prior to theriveting operation, is underthe control of the operator through his control of the motive fluid conveyed to either end of the cylinder l9'through the pressure, supply pipes 25 "and 26, as best shown in Fig. a, said cylinder being provided with the stuffing box 23.

The operation is as follows Referring now to the control by the op erator of the fluid supply, which first throu h the pneumatic holder-on, comprising the fixed. cylinder 19, piston 21 and piston rod or plunger 20 enables him to position the movable riveter 15 relatively to the fixed riveter 11 and then after such positioning enables him to effect the riveting operations, it will be apparent that the air supply pipes and 26 of the cylinder 19extend down as best seen inFigs. l and 2 to a left hand air valve 31 the lever 36 offwhich is" connected with a pedal rod 35. extending up through the foot plate 9 to the left-hand pedal which after depression by the operators left foot is'elevated to normal positionby a spring or other tension device 34 interposed between it and the "foot plate 9,-so that by the proper depression of said pedal the operator can admit air to the cation of the hammering 'pistons of both riveters is effected by the supply of motive fluid through the supply'pipes 27 an'df28,

which extend from the respective f riveters downwardly-(see Fig. 2) :to a right hand air valve 33, the lever 39 of which is connected with the pedal rod'38 extending up through the foot plate-9 to'the right-hand pedal 32, which after depressionby the op,- erators right foot is elevated to normal po-' sition by a spring orother tension device 37 I interposed between it and the foot plate 9 ,so that by the proper actuation of said right-hand pedal, theoperator can control the *inlet and exhaust to the distribution valves of the two riveters. The positions of the fixed and removable riveters 11 and 15 can be reversed without departing from the spirit of my invention.

It will be apparentfrom the foregoing that the operator withwone foot ashis left foot can readily control the action of the pneumatic holder-on, seen at the right of Figs. 1,8, and 4, andwith hisother foot as the right can control the starting and stopping of the reciprocations of the hamjmering pistons of the fixed and adjustable riveters 11 and 15, all withoutfatigue, and in addition the operator is not subjectedto the jar and vibration-incident to the opera- I tion of the riveters. By theiconjointoperation of the two alined' riveters the rivets will be expeditiously and effectively driven, since the pneumatic holder-on coa cts: in a very effective manner during the riveting operation as will be evident to-those skilled in the-art. I g p .s

I have deemed it unnecessary to show in detail the constructionfof thefoot operated "valves 81 and 33,, since it, will be apparent that any suitable cook or valve which will control or cut ofi the inlet' of'the motive fluid in the manner described will be effective for this purpose, While I preferablyl 7 Letters Patent, is

employ the well known Boyer riveter, it -will be evident that. any other conventional type of pneumatic-riveter may be employed without departing from the spirit ofmy invention.

It will now be apparent th ai .have'devised a novel and useful constructionof a double riveting machine which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and'while I have, in I the present instance, shown and described a preferred embodiment thereof which will be found in practice to give satisfactory and reliable results, it is to be understood that'the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificingany of its advantages.
